x86: tsc: Rename X86_TSC_TIMER_EARLY_FREQ to X86_TSC_TIMER_FREQ

2021-08-02T07:11:40+00:00

Currently there are two places to specify the x86 TSC timer frequency
with one in Kconfig used for early timer and the other one in device
tree used when the frequency cannot be determined from hardware.

This may potentially create an inconsistent config where the 2 values
do not match. Let's use the one specified in Kconfig in the device
tree as well.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

x86: tsc_timer: Correct overflow in __udelay()

2021-02-01T07:11:40+00:00

At present long delays such as msleep(2000) can cause an overflow in this
function. There is no need for this, since it already uses a 64-bit int.

Add a cast to correct this.

x86: apl: Reduce size for TPL

2021-01-05T19:24:41+00:00

Update various drivers to use of_match_ptr() and to avoid including debug
strings in TPL. Omit the WiFi driver entirely, since it is not used in
TPL.

This reduces the TPL binary size by about 608 bytes.

x86: Fix up driver names to avoid dtoc warnings

2020-11-05T06:58:45+00:00

At present there are a lot of dtoc warnings reported when building
chromebook_coral, of the form:

   WARNING: the driver intel_apl_lpc was not found in the driver list

Correct these by using driver names that matches their compatible string.

timer: Return count from timer_ops.get_count

2020-10-22T13:54:53+00:00

No timer drivers return an error from get_count. Instead of possibly
returning an error, just return the count directly.

x86: timer: Reduce timer code size in TPL on Intel CPUs

2019-12-15T03:44:10+00:00

Most of the timer-calibration methods are not needed on recent Intel CPUs
and just increase code size. Add an option to use the known-good way to
get the clock frequency in TPL. Size reduction is about 700 bytes.

Note that version 1 of this commit caused bootstage to crash since the CPU
was not identified. This is corrected by changes previously applied to
make sure that the CPU is identified before spl_init() is called, such as
